Hi guys, I have tried everything and looking for any possible answer but I am lost .. please help me here. This is my 2nd CentminMod install ... Currently using Standard setup + fastcgi_cache + ngx_pagespeed. (Everything is done following guides here and forum) Site is working fine but I am randomly getting issue with rewrite. The browser will show 404 Not found error and the log will show Code: 2014/12/06 11:17:45 [error] 15989#0: *22 "/home/nginx/domains/domain.com/public/2012/10/31/my-old-post-title/index.php" is not found (2: No such file or directory), client: x.x.x.x, server: domain.com, request: "GET /2012/10/31/my-old-post-title/ HTTP/1.1", host: "domain.com" My permalink settings are Code: Custom Structure: http://domain.com/ %year%/%monthnum%/%day%/%postname%/ The site is running WordPress and forum but the issue is happening with just WP. I may be going out of my mind but I think it's happening more when using Chrome ... Less with FireFox. And it will not happen on all posts. Sometime same blog post will work fine, and then give the above error. Please help me, what to do, where to start looking? Domain config file attached.
